Wow, these are looking great, Don!  Will you include any instruments or tips on where to find them?  I have to agree with kuroyume about the guitar.  I haven't played mine in awhile (between carpal tunnel disorder and the ensuing surgery) but I know my arms would be really tired if I had to hold that arm position for long.  However, I played classical style on a Western acoustic and used the shoulder strap to support the weight of the gutiar so I'm not sure how an actual classical guitarist supports the body of the guitar.
